Joni, I have finally had some success in linking some of the Cass County, Iowa, Ackermans, and I am feeling more confident that your Caroline is possibly a sister of the others. I have documents not that indicate that Henry, William (who later moved to Alliance Nebraska), and John Henry are all sons of Englehart and Katharine Ackerman. Englehart is buried in the old German cemetery south of Griswold. Because of Henry's interaction with Valentine (witness to marriage) and Peter (executor of estate), it is most likely that they are also related. They all came to Cass County the same time as your Caroline, first going to Atlantic before purchasing land and locating in Noble Twp., Cass County, and Douglas Twp., Montgomery Co. Please contact me.
